Still trying to visualize your layout.

If you have you have 220 (240) you have 110 (120). How are you going to tap into the 240V? If it an unused 240v recepticle, you can easliy split/convert it to 2x120v (like done for kitchen plugs)

220 comes from a base board heater , (we dont use electric) but because there are other heaters in the curcuit, I cant split the curcuit into 110
